PROBLEM TO BE SOLVED: To provide a bio-degradable film for twist wrapping having excellent peeling performance from a candy. SOLUTION: The film for twist wrapping is a biaxially-oriented film mainly comprising a polylactic acid-based polymer, and contains a 0.01-1.0 mass% low molecular weight polymer, and the low molecular weight polymer is a poly-olefin. The number-average molecular weight of the low molecular weight polymer is 1,000-8,000, and a melting point is 60-140°C. The polylactic acid-based polymer contains 1-10 mass% aliphatic-aromatic copolymerized polyester. COPYRIGHT: (C)2006,JPO&NCIPI
